Is the joint brochure of the graphic and text fast printing store always missing pages? Sunlife Hot Melt Adhesive Selection Story for a Store

Is the joint album of graphic and text quick printing always missing pages? Sunlife in a storehot melt adhesiveSelection story

Lao Zhou opened a graphic and text fast printing store in the urban area, often accepting short editions of enterprise joint brochures and conference manuals. Recently, there have been more and more customer complaints: the spine of the booklet drops after flipping it a few times. At first, he thought it was because the glue assembly machine was old and the problem still existed after replacing it with a new one.

The problem lies with the rubber particles

The technician came to take a look and found that Lao Zhou was using low-priced hot melt adhesive granules from miscellaneous brands. After melting, the viscosity was insufficient and the penetration was poor, making it difficult for the paper fibers to bite. Co branded books often use copperplate paper weighing over 200g, which requires higher initial adhesion and penetration of the adhesive. After changing several samples, we finally found a high viscosity book and magazine granule for Sunlife hot melt adhesive.

Changes after changing the adhesive

• The coating temperature is set at 175 ℃, and the spine is evenly brushed without any blank glue channels.
• The joint brochure was repeatedly reviewed and spread out on the desktop without any pages falling off, and the customer accepted it on the spot.
• For the same booklet, the glue consumption is slightly reduced because there is no need to stack thick glue for good penetration.

Three selection points summarized by Lao Zhou

Firstly, do not be greedy for cheap use of universal granules for short version fast printing, and use high viscosity copperplate paper; Secondly, identify manufacturers with stable supply. Each batch of Sunlife hot melt adhesive from Guangzhou Sunlife Trading has consistent parameters and will not stick today or tomorrow; Thirdly, first test the sample on your own machine, don’t stock up based on intuition.
